For the last ten years or so, I used to maintain a list of conferences in the area of analysis & PDE (see e.g. this page for a partial archive of this conference list). However, due to many other demands on my time, I eventually ceased to maintain it, instead passing it over to the Harmonic Analysis and Related Problems (HARP) group that was supported by the European Mathematical Society. Unfortunately, the EMS funding ran out a few years back, the HARP group dissolved, and so the page drifted for a while.
